Abstract

The complete chloroplast genome sequences of the wild flowering cherry, Prunus yedoensis Matsum., which is native and endemic to Jeju Island, Korea, is reported in this study. The genome size is 157 786 bp in length with 36.7% GC content, which is composed of LSC region of 85 908 bp, SSC region of 19 120 bp and two IR copies of 26 379 bp each. The cp genome contains 131 genes, including 86 coding genes, 8 rRNA genes and 37 tRNA genes. The maximum likelihood analysis was conducted to verify a phylogenetic position of the newly sequenced cp genome of P. yedoensis using 11 representatives of complete cp genome sequences within the family Rosaceae. The genus Prunus exhibited monophyly and the result of the phylogenetic relationship agreed with the previous phylogenetic analyses within Rosaceae.

摘要

本研究报道了韩国济州岛本土特有的野生樱花——江户彼岸樱(Prunus yedoensis Matsum.)的完整叶绿体基因组序列。基因组长度为157786 bp,GC含量为36.7%,由85908 bp的大单拷贝区(LSC)、19120 bp的小单拷贝区(SSC)和两个各为26379 bp的反向重复序列(IR)组成。叶绿体基因组包含131个基因,包括86个编码基因、8个rRNA基因和37个tRNA基因。利用蔷薇科内11个完整叶绿体基因组序列的代表,进行了最大似然分析,以验证新测序的江户彼岸樱叶绿体基因组的系统发育位置。李属表现出单系性,系统发育关系结果与蔷薇科先前的系统发育分析一致。
